I would use equal temperament. I would only use something else if I had a guitar with some kind of Buzz Feiten system or some fanned frets, etc.

I've read about, but have no direct experience with people using slightly different intonation temperaments in order to get their open tuning chords to sound more "beatless". However, if you play standard pop-rock using standard tuning, then I suggest equal temperament.

I've got an old Peterson strobe. I used it for piano tuning. Just another paid skill back in my working musician days. :) They are handy because you have to do this to get a piano to sound "right". Look halfway down the page.

I also remember that a strobe tuner (usually a Peterson) was the standard machine for tuning brass in most big bands & orchestras I've played in. You can spend a good hour sitting around waiting for each brass guy to have his turn in front of the Peterson, fine tuning his horn crook until his B-flat (or E-flat) is in tune. And it's worth it! Ever hear a high school marching band and the brass is "all wonky"? Someone doesn't know how to or didn't use a strobe tuner. :)

So, I think the other temperaments are more useful for instruments other than guitar.
